I am getting the error : signature failed validation - installation details may have been altered

[akashitidol]

Hi everyone,
Getting this issue when I am uploading the BUF and SDP files on Test REC:

"
Error: Please check and correct the following issues before continuing:
Signature failed validation - installation details may have been altered
"

I have created Self signed certificate and serial number on our server using below commands,

openssl x509 -in 1808techformcert.pem -pubkey -noout > 1808public_key.pem
openssl rsa -in 1808techformcert.pem -noout -modulus

• After generating certificate and serial number, I have added that on git (https://github.com/CleanEnergyRegulator/TEST-SPV/blob/cer-endpoint-fix/TEST-referencedata.json)

• I have replaced the above mentioned informations in application signature(Signature 2) from our code,

  1. X509IssuerName (Certificate Subject)
  2. X509SerialNumber (Certificate Serial Number)
  3. X509Certificate (Public Key)
  4. KeyName (Certificate Subject)

  Can anyone guide me for how to resolve the issue?

-----------------------------------------------------------Code to sign XML---END-------------------------------------------------------------

Also , I want signature in below format and tags . I am removing ds from sign after XML was signed, may be due to that i am getting
this error "Signature failed validation - installation details may have been altered".
